I visited a couple one time in their home who complained about a niece who got married. All the invitations were sent out and everything was in order but they never received a thank you card for the gift they sent. They were very upset. I asked them if it was a gift they sent. They said yes. Then they shouldn’t expect a thank you card because the definition of a gift is that it has no strings attached.
